Maria-Gabriella Di Benedetto obtained her Ph.D. in Telecommunications in 1987 from Sapienza University of Rome,
Italy. In 1991, she joined the Faculty of Engineering of Sapienza University of Rome, where currently she is a Full Professor of Telecommunications.
She has held visiting positions at the Massachusetts Institute of Technology, the University of California, Berkeley, and the University of Paris XI,
France. In 1994, she received the Mac Kay Professorship award from the University of California, Berkeley. Her research interests include wireless
communication systems, in particular impulse radio communications, and speech.
Seminar Title: "Closed Form Asymptotic Expression of a Random-Access Interference Measure"
Abstract: A model describing the cumulative effect of the independent access of K users to a shared resource, which is formed by N elements, is proposed, based on which an integer interference measure ζ is defined. While traditional cases can be reconducted to reference well-known results, for which ζ is either Gaussian or Poissonian, the proposed model provides a more general framework that offers the tool for understanding the nature of ζ . In particular, an asymptotic closed form expression (K → ∞, N → ∞, K/N → β ∈ (0, ∞)) for ζ distribution is provided for systems presenting constructive versus destructive interference, and is applicable to characterising statistical properties of interference in a wide range of random multiple access channels.
